This seems to be bash syntax (the "[[" can (and should) be easily avoided)

Another question:
Is this related to perl or Mac OS ?
The commit message is indicating that the combination of Mac OS 10.10.1 
and perl 5.18.2
is working, but the code does not reflect this.
Does it make sense to test for the perl version in the code?
Or is it OK to mention

  Under Mac OS X 10.10.1 which ships with Perl 5.18.2, this problem....
